Question

What strengths and limitations do the clinical (or case study) method and ethnography have in common?

Distinguish among age-graded, history-graded, and non-normative influences on lifespan development. Cite an example of each in Sofie’s story at the beginning of this chapter.

What is epigenesis, and how does it differ from range of reaction and genetic–environmental correlation? Provide an example of epigenesis.

Links between family and community foster development throughout the lifespan. Cite several examples from our discussion that support this idea.

ANSWER

Clinical method and ethnography both are research method that used commonly in research to study human development. On the other hand, both research methods are used commonly in the research method and both techniques are descriptive qualitative in nature. These two methods shared a common strength that both techniques present a thorough perceptiveness of the study in many aspects that human development. The limitation of two methods shared lie on the fact that whatever the findings are potentially strong and influenced. It has been found that theoretical research preferences are prejudiced by the investigator. The Investigator impose his cultural conscience that misinterprets what they see. The findings of these two methods are not applicable in the general population but are applicable for the single subject only. The result is applicable only for a specific subject not for the general population.

• The age-related influences of biological and sociological events were related to the age of a person, for example, we can say that physical maturation during the childhood of a person.
• The historical related influences are that determine the environment and the social events that affect a large number of population at the same time.

Epigenesis is a theory that explains the embryo that develops from the successive differentiation of originally undifferentiated physics. It is different from the genetic environmental and the range reaction correlation.
The non-normative influence is the influences that include all age-related influence, history-related influences and the pattern of the life cycle that is related to the non-normative influences.
For example, twins are brought up in different environments that have the same genetic code. There genetic code slightly different because they have been brought up in a different environment.
Family and community play a vital role in the nature and nurture of human development. Family and the community that has been fostering the development of human being, both have attended the church. Both have wor-shipped their religion. So that family and community play a great role in the development of a child. Children see their parents worship the same religion in the same church.
